• Just curious if a 1.9TD (aaz) crank is the same as a TDI crank.
  
  Just looking for options to this crank pulley upgrade for the fabled wobbly pulleys on the TD.

• yes, its the same. When my pulley started its death wobble its the route I went. I believe its NW fuel injection down the road in van that can machine your crank in place to accept a tdi pulley or pop it out & have it machined to fit. There have been a few alternative methods successfully tried too.

• which method would you think is the better one?  im sure machining the stock 1.9td crank would be the most cost effective one but at the same time this is a rebuild engine so a new crank wouldn't hurt either.

• I know there are others here who have tried all the options so stand by...

• I have done a re-machined crank to accept the TDI pulley.....done by fastTD! no problems or complaints there....excellent work - this was done on my sisters car while I was rebuilding the motor after a TB broke.
  
  My golf im running a new bolt and gear with 2 dowel pins. I didnt want to pull/rebuild the motor, so thats why I chose this method. I plan on using the same one on the motor I will be building for my corrado.

• The only TDI cranks you can use as direct replacements are the 1Z and AHU. The others have an oil pump gear on them.
